LUMBER-MEASURE.

SPECIFICATION forming part of Letters Patent No. 307,675, dated November4, 1884-.

' Application filed June 12, 1884.

To coZZ whom it may concern.-

Be it known that I, EARL O. NEWTON, a citizen of the United States,residing at Batavia, in the county of Kane and State of Illinois,haveinvented certain new and useful Improvements in Lumber-Measures; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a side view of my device with one of theside faces removed. Fig. 2 is a longitudinal vertical sectional view ofthe same, and Fig. 3 is a side view.

This invention has relation tolumber-measuring machines; and it consistsin the con struction and novel arrangement of devices, as hereinafterset forth, and pointed out in the appended claims.

In the accompanying drawings, the letters A A A A representtraverse-wheels, which are made of diiferent sizes to correspond withdifferent lengths of boards, so that when one of said wheels is rolledacross a board of cor-- responding length it will indicate the number offeet in the board on the dial U of the machine. Each traverse-wheel A isprovided with a pinion, D, which engages the large cogwheel B,and whenthe corresponding traversewheel is rotated moves said cog-wheel. The huba of the cog-wheel B is seated onthe center pin or pivot, b, and isprovided with a striker-arm, E, which, at every revolution of the wheelB, engages a tooth of the toothwheel G, moving the latter one step. Apinion, F,,is attached to the toothed wheel G,

which engages andoperates the cog-wheel O, which has its bearing on theaperture of the dial V.

H represents the inner case of the machine, which covers in all themechanism except the outer portions of the traverse-wheels A.

J represents the outer-case wall, which covers all the traverse wheelsexcept that one which is to be used, an opening being left in the outercase for the traverse-wheel, which is brought to said opening by turningthe inner case, H, on its center bearings.

(No model.)

0 represents a spring-dog, which engages the toothed wheel G and keepsitfrom turn ing, except when moved by the arm E. The screws I connect thewalls of the inner case, H, together.

To the hub of the wheel B is fastened the long indicator-hand S, whichpoints out upon the dial the number of feet from one to one hundrr d.The short hand R is fastened on the hub O of the cog-wheel 0, andindicates on the dial the number of feet from one hundred to tenthousand. The dial U is formed on-the front of the cam H.

L represents a latch, which is connected to the outer case, J, and isadapted to engage catch-bearings c of the inner case, H, to pre vent thelatter from turning. The latch L is held to its duty by a spring, N.

P represents that portion of the inner case which forms a journalrevolving in the bearing d of the outer case, and Q is a plate which issecured to the journal portion P by screws, and serves to hold the caseJ to the case H. The traverse-wheels and their pinions are provided withjournals 6, which run in bearings in the frontand back of the innercase, H. The toothed wheel G and its pinion run on a screw-stud, g, andthe cog-wheel 0 runs in a bearingaperture in the center of the dial U.There is, therefore, no connection or friction between the hands Rand-S. The dial U is provided with an outer scale, h, and with an innerconcentric scale, 70. The outer scale,indicated by the long hand S,shows the number of feet from one to one hundred. The inner scale,indicated by the short hand B, shows the number of feet from one hundredto ten thousand. The outer case is held together by the screws V V. Thehandle K is connected to the outer case.

In operating this device, first turn the hands so that they will bothpoint to the cipher on the dial 5 then disengage the latch L and turnthe inner case so that the largest wheel A will be in position for use.This wheel is designed to be of the proper size to measure boards twelvefeet long. When rolled across a board have made one full revolution, andthe arm E will move the wheel G one tooth, thus moving the hand B onepoint on the dial. This operation can be continued until the hand R hasmade one full revolution, indicating ten thousand feet on the dial. Thisis, of course, the surface measure, representing boards one inch thick.For thicker boards, it will be necessary to add to the amount indicatedon the dial as, for instance, if the boards are one and onefourth inchin thickness, one-fourth of the amount indicated on the dial must beadded; thereto. If the boards are two inches thick, the amount indicatedshould be doubled. The traverse-wheels are designed for boardsrespecti-vel y twelve, fourteen, sixteen, and eighteen feet long. Theseare the most common lengths; but the machine may be made to measureother lengths of boards by adding other wheels. For long boards, themeasure ment may be made by addition-as, for example, in measuringtwenty-foot boards, use the sixteenfoot wheel and add one-fourth to thaamount indicated on the dial.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a board-measure, the combination, with traverse-wheels ofdifferent size, respectively provided with pinions, of the-toothed wheelBandits long hand, the toothed wheel 0 and its short hand, the wheel Gand its pinion, the arm E, the dog 0, the adjustable rotary inner case,H, and its dial, substantially as specified.

2. In a board-measure, the combination, with the outer case, of anadjustable inner casccarrying a dial, traverse-wheels of different size,gearing, and indicating-hands, substantially as specified.

3. In a board-measure, the combination, with the outer case, J, and thelatch L, of the inner case, H, and i s dial, the traverse-wheels ofdifferent size, their pinions, the cog-wheels B and G and their hands,the wheel G,its pinion, and the arm E and dog 0,-substant-ially asspecified.

4. In a board-measure, the adjustable trav crsc-Wheels geared to move anindicator over a dial, and adaptedv to be rolled across boards for thepurpose of measuring the same, substautially as specified.

In'testimony whereof I affix my signature in presence of two witnesses.

EARL O. NEWTON.
